Seminar Puzzle

This puzzle is based off of seminars, which are special days where students can sign up for classes that are not part of the traditional curriculum. I’ve attached a sample of the seminar listings to this page so that you can compare. You may need to consult it to find the final answer. This puzzle is a PDF, and is the first link.

This puzzle is part of a puzzle series that I am making. If you have an answer, check it here:
